Found this insect in my house. Is it normal this time of year? Is it normal in my region, Cleveland? Could you tell me what it is? When confronted, it raised what I assume is its back end as if it would sting me or shoot something out. Is it anything to be concerned about?
This is a Rove Beetle in the family Staphylinidae, and the threat posture is common with many members of the family including the Devil’s Coach Horse. Most Rove Beetles, including we suspect your individual, are perfectly harmless, though one genus, Paederus, can cause contact dermatitis. Paederus Rove Beetles sport black and red warning coloration and they are known as Creechie Bugs in Africa.
